160ml heat-resistant glass baby bottle with a 4-stage adjustable nipple. I was exclusively breastfeeding before my baby was a month old, so I only used this bottle twice, putting in about 10ml each time, right after I was discharged from the hospital after giving birth. The nipple pin has never been used (as shown in photo 6, it's still attached to the box). After use, the nipples were sterilized, wrapped in plastic wrap, and stored. - Brand: Combi - Model Name: teteo Nursing Textbook - Material: Heat-resistant glass - Features: 4-stage adjustable nipple - Intended Use: For feeding - Size: 160ml Thank you for looking.
